Polar Bond - the attractive force that hold atoms together that share electrons unevenly (diapole) Polar Molecule - a molecule with two partially charged ends, lopsided for charge (diapole) Which molecules have diapoles and which ones ARE diapoles? HCl CO2 H2O F2

Electronegativity - the ability of an atom to attract and hold on to an electron from another atom

Electronegativity Periodic Trend
